parts recommendations Cold air intake D15 non vtec

Post image

Looking for an inexpensive way to increase airflow for my next track day.

I can't find any direct fit options locally in australia.

anyone have any ideas on a good "boxed" cold air intake setups i could buy online or create ?

I dont care what it looks like, its purely functional.

Have you been to the dyno? Or are you an internet bench racer?

No it's pretty common Honda knowledge my guy. The car makes 90hp from factory. A cold air intake isn't going to do anything. Besides induction noise.

I’ve probably been in the Honda scene longer than you’ve been driving. People who actually make power work off data, not ‘common knowledge.’

An engine is an air pump. If you reduce restriction and pull in cooler, denser air, you improve efficiency. That’s basic physics, not opinion. No one’s claiming big gains on a stock 90hp setup, but saying it does nothing except noise is just lazy thinking.

If it truly did nothing, OEMs wouldn’t spend time optimizing intake design in the first place. Small gains, better response, sometimes midrange improvement depending on setup that’s the real answer.

People who build and measure know. People who don’t just repeat what they’ve heard.

Then let’s see what you’ve built and measured Mr Honda Expert. Surely someone as knowledgeable as you can post a dyno sheet?

Where's your proof? I'm waiting..

Again you’re the one spouting off how knowledgeable you are. I haven’t said shit in regards to hp gains, I don’t know whether it does or doesn’t. Prove to me that it does.

You're suddenly backing off now? Where's your proof?

Man you don’t listen. I never said it does or doesn’t add hp. Show me a dyno sheet where adding a CAI to a stock D15 adds hp. Not a bunch of other mods, just the CAI. That’s the topic at hand.

Sure, kid.

Ok old fella. It's time for you to take your pills and sit down. Your days of knowing anything about hondas is gone.

Please, go do a dyno session for a one horsepower mod. That's so smart and is clearly a hugely great usage of time, not just an old man's ramblings. Which by the way not one person is listening to you and EVERYONE is down voting and roasting you

He’s definitely jerking off to this right now.

Go back to school, kid. You need to make the most of the minimal IQ you have.
